Johnson Controls (NYSE: JCI) makes car interiors and heating, ventilation, and air conditioning (HVAC) products. The company's car parts business is shrinking with the overall US automotive business (the company's automobile sales fell 34% in 2009). Although Johnson Control's automobile components sales generated 42% of 2009 total revenues, the segment lost the company $541 million for the year.
The company is relying heavily on its Building Efficiency and Power Solutions segment, both of which generated the about same amount of segment income at $400 million.
Johnson Controls is one of the few companies, other than energy companies, that is benefiting from higher electricity prices. US electricity prices increased an average of $0.31 per kilowatt hour in 2009, and higher electricity costs encourage building managers to replace their heating and air-conditioning systems with newer, more energy-efficient equipment.
In 2009 U.S. sales of automobiles fell to 10.4 million new cars, making it the worst year in terms of car sales in 27 years. The economic slowdown and the instability of the Big Three Automakers is making is more difficult for people to buy cars. When consumers purchase fewer cars, automobile companies buy less interior products from companies like Johnson Controls as they decrease production to meet lowered demand. Despite attempting to minimize the effects of decreased automobile demand by negotiating contracts, Johnson Controls' Automotive Experience revenues decreased by $6 billion dollars between 2008 and 2009.
Because Johnson Controls reports their revenues in U.S. dollars but does 52% of their business outside of North America, it is exposed to fluctuations in exchange rates. If foreign currencies appreciate, the dollar value of Johnson Controls' international revenues increases.  In 2009, the unfavorable impact of foreign currency translation was -$2.1 billion.
